Errr, what? Why do you think the load average is high?

Load average is defined as a number of processes in the run queue (i.e.
using or waiting for a CPU). So the load average "0.88 0.94 0.87" means
there was less than one process waiting for CPU most of the time. I
wouldn't call that "high load average", especially not on a 32-core
system.
